Abstract: A printed circuit board (PCB) includes a base board, a conductive pattern arranged on the base board, and a number of metal pads arranged on the base board. The conductive pattern includes a number of vias and traces. The metal pads are evenly arrayed where there is a sparsity of vias and traces to balance a current during a plating process for achieving an even plating thickness. A method of designing the PCB includes: simulating a PCB with electronic components using a software, simulating vias, traces, and metal pads, and testing the electrical characteristics of the whole simulation. If the simulated PCB fails testing then it is redesigned. Once a simulated PCB passes testing then it is ready to be manufactured.

Abstract: Cytotoxic T lymphocytes (CTLs) specific for antigenic peptides derived from IgE molecule can be generated in vitro by stimulating resting naive CD8 T cells with IgE peptides presented by artificial antigen presenting cells. The IgE specific CTLs lyse the target cells loaded with IgE peptides in vitro and inhibit antigen specific IgE response in vivo. In addition, adoptive transfer of the IgE specific CTL to an asthmatic mouse model can inhibit the development of lung inflammation and airway hypersensitivity. IgE specific CTL provides a treatment for allergic asthma and other IgE-mediated allergic diseases. Antigenic peptides identified from non-tumor self-antigens induce specific cytotoxic T lymphocyte (CTL) in vitro. The CTL induced by peptides identified from CD40L can kill activated CD4 T cells. In vitro generated CTL specific for CD40L inhibit CD4-dependent antibody responses of all isotypes in vivo.

Abstract: A method of screening a subject for a proliferative disease risk factor comprises detecting the presence or absence of upregulation of the CLN3 gene in the subject. The upregulation of the CLN3 gene in the subject indicates the subject is at increased risk of developing a proliferative disease. Methods of screening compounds for the treatment of proliferative diseases based on the CLN3 gene and its product are also disclosed, along with methods of treating such diseases and vectors useful therefore.

Abstract: In order to transmit data packets between a wirelessly connectable communications device and a communications partner, particularly during a handover process, the invention provides that when a first wireless transmission path is available, an availability of at least one additional wireless transmission path is detected. Based on the detection, a specific assignment schema, via which at least one portion of the data packets is assigned to each of the transmission paths, is selected according to specific transmission requirements and/or to a transmission protocol to be used for transmitting the data packets. An address specification specific to the transmission path is then assigned to a respective data packet that is assigned to a transmission path. By using the assigned address specifications, the data packets are transmitted via the different transmission paths between the communications device and the communications partner according to the selected assignment schema.

Abstract: A power jack (1) includes a dielectric housing (10) and a central terminal (20) received in the dielectric housing. The dielectric housing includes a mating face (11), a cavity (130) in the mating face and an anti-mating portion (15) formed on an inner face of the cavity for preventing full insertion of a non-complementary power plug having a smaller transmission power than that of the power jack. The central terminal includes a contact section (21) extending into the cavity for electrically connecting with a complementary power plug.

Abstract: A method of preparing non-platinum composite electrocatalyst for a fuel cell cathode, comprising: (1) preparing a carbon supporting titanium dioxide; (2) compounding the carbon supporting titanium dioxide with a transition metal macrocyclic compound in an organic solvent to produce a carbon supporting titanium dioxide-transition metal macrocyclic compound comprising 0.1–5 g/L of macrocyclic compound; and (3) thermal treating the resulting compound in step (2) at 100–1000° C. to produce a composite catalyst. The composite catalyst prepared with the method according to the present invention also has the advantages of better resistance to methanol and lower cost over the Pt/C catalyst. The said composite catalyst would have better prospects in application.
